Almond flour vs ground almonds

Open three different recipes and you may find three different names for what looks like the same powdery ingredient: almond flour, almond meal, ground almonds. They are close relatives, but not always interchangeable. Knowing the difference can save a cake from turning heavy or a batch of biscuits from spreading into one big sheet.

The short version

Both are simply almonds that have been ground up. The differences come down to three things:

1. Whether the skins were removed first. Blanched almonds have had their brown skins taken off. Unblanched almonds keep them.
2. How finely they are milled. A powder can be coarse and sandy or very fine and soft.
3. What the label calls it. Naming varies by country and by brand, so the words alone do not tell you much.

In general, "almond flour" suggests a finer, paler powder made from blanched almonds, while "ground almonds" or "almond meal" can be slightly coarser and sometimes speckled with skin. But there is no strict rule, so read the packet.

What blanching changes

Blanching removes the thin brown skin. Skinless almonds grind to a pale cream colour with a smooth, even texture. Skin-on almonds give a speckled, slightly darker powder with a touch more bitterness and a rustic look.

• Blanched: best for pale cakes, delicate sponges, macarons and anything where colour and smoothness matter.
• Unblanched: fine for brownies, rustic tarts, muffins and anything dark or spiced where the skins disappear.

Our ground almonds are a good everyday choice for sponges and tarts. Always check the product page for details on whether skins are included.

Texture and grind

A fine grind absorbs liquid differently and produces a tender, even crumb. A coarser grind gives a slightly sandy, moister result with more bite.

For most home baking, the difference is small. Where it matters:

• Macarons and French-style meringues: fine, blanched flour is a must. Coarse particles make the shells bumpy and prevent them from rising smoothly.
• Cakes and frangipane: either works, though finer will be silkier.
• Biscuits and cookies: coarse can add pleasant texture.
• Breading and crusts: coarse is fine, even preferred, for a crunchy coating.

If your almond powder feels damp or clumpy, it may have been overground. Overgrinding releases the oils and starts to turn the powder into a paste, so stop as soon as it looks like fine crumbs.

Making your own

You can grind almonds at home with a food processor, though it takes a little care.

1. Start with whole raw almonds. If you want blanched flour, blanch them first: pour boiling water over them, leave for 1 minute, drain and slip off the skins. Dry them completely.
2. Make sure the nuts are fully cool and dry. Warm or damp almonds turn to paste.
3. Use short pulses, not a continuous run. Pulse for one or two seconds at a time.
4. Stop when you have a fine, sandy powder. This usually takes 30 to 60 seconds in total.
5. Sift out any larger pieces and grind them again.

Add a spoonful of sugar or flour from the recipe to the bowl as you grind. The dry ingredient soaks up some of the oil and helps prevent paste. Homemade powder is best used within a few days, or stored in the fridge, since fresh grinds lose flavour quickly. If you ever end up with a paste by accident, congratulations: you have made almond butter. See homemade nut butter in a food processor for how to do that on purpose.

Swapping in recipes

Can you swap one for the other? Usually, yes, with a few caveats.

• Cakes and tarts: swap freely, though expect small differences in colour and crumb.
• Macarons: stick to fine, blanched flour.
• Gluten-free baking: almond powder replaces wheat flour only partly. It has no gluten, so it needs eggs, binders or a flour blend. Follow a recipe designed for it rather than swapping one-for-one in a wheat recipe.
• Weight vs volume: a cup of almond flour and a cup of ground almonds can weigh slightly different amounts. Weigh by grams if the recipe gives them.

If a recipe lists "almond meal", ground almonds are a safe substitute for most uses.

Don't confuse it with flaked almonds

Flaked almonds are thin slices, not ground powder. They are meant for scattering over bakes, toasting for texture or folding into granola. If you want to see how they fit into everyday recipes, our baking category has the full range.

A note on allergens

Almond powder is a tree nut product. Anyone with a tree nut allergy should avoid it and read every label carefully, since almond flour appears in unexpected places such as gluten-free mixes and some sauces. See nut allergies and reading food labels for general guidance.

Storage

Ground almonds have much more surface area than whole ones, so their oils are exposed to air more readily and they go stale faster. Keep the bag tightly sealed and store it somewhere cool and dark. For longer storage, an airtight container in the fridge helps. You can learn more about the almond itself on its Wikipedia page.

A last word

Check whether your powder is blanched, check how fine it is, and match it to the job. For most cakes, either works. For macarons, go fine and pale. And if the recipe calls for something you do not have, a quick pulse of whole almonds is only a minute away.
